linux-2.6.24: deactivate the LEON co-processor for hipox machine
There are massive network problems when transmitting UDP packets using the
LEON copro. UDP packet contents get overwritten at the sender side, UDP
checksums are incorrect, and the like. The problem can be triggered by
writing small (< MTU size) packets into a socket in rapid succession to
multiple receivers on a system without any other load. Until we can fix
the LEON firmware we disable it.
